RESUMO

Euryale ferox (also known as foxnut), belongs to the family Nymphaeaceae. It is mainly grown in India, China, Japan, and Korea. It is a highly nutritious food, abundant in nutritional and bioactive compounds such as carbohydrates, protein, fiber, vitamins, minerals, and polyphenols. It is considered a functional food owing to its various health benefits such as antidiabetic, antihyperlipidemic, antifatigue, hepatoprotective, cardioprotective, antimelanogenic, etc. E. ferox has immense potential in both food and non-food industries. Regardless of being recognized as a superfood packed with nutritional as well as medicinal properties, it is still neglected, and there has not been much attention given to its cultivation. Therefore, in this review, the potential of E. ferox as a superfood has been explored to enhance its utilization in the development of different foods and make it available outside its growing area. PRACTICAL APPLICATIONS: Euryale ferox is abundant in several macronutrients and micronutrients; and considered as a superfood in terms of various health benefits. E. ferox has the ability to be used in the development of different health, functional, and nutraceutical foods, which will open a new door for the food industry to combat with numerous diseases.

RESUMO

The purpose of this review is to analyze factors that influence individuals' decisions to participate in clinical trials focusing on racial and ethnic disparities that exist in clinical trials. These factors are then used to develop a survey that may be used in a clinical setting to further understand specific factors affecting participation. A comprehensive search of electronic databases was carried out for publications from 2010 to 2021 using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. After reviewing the data, the predominant factors that were encountered in the search were then commented upon and reviewed to create an evidence-based questionnaire. ​​​​Using the comprehensive search, factors that affect clinical trial participation were identified. These factors were then used to create a comprehensive, evidence-based questionnaire to be implemented in a clinical setting to conduct and analyze the factors impacting participation in clinical trials. â€‹â€‹â€‹â€‹â€‹â€‹â€‹Understanding the factors that primarily impact an individual's decisions to participate or not participate in a clinical trial allow researchers to implement changes to decrease the hesitancy regarding participation.

RESUMO

Radiotherapy is one of the commonly used treatments for cancer. A compensator is a device used in intensity modulated radiotherapy (IMRT) treatments to compensate for the irregularities of the body. One can provide a more uniform distribution of dose for the treatment of tumors using compensators in IMRT to obtain a better therapeutic outcome. A variety of compensators are used in IMRT. One high Z (cerrobend), two medium Z (brass and steel) and one low Z (lucite) compensators are selected for the present study. The mass attenuation coefficients have been computed in an energy range of 15 keV to 15 MeV using XCOM program and the Monte Carlo N-particle-5 (MCNP5) code. The percentage deviation between the values indicates that the mass attenuation coefficients obtained using both the methods are in good agreement. These values are further used to calculate the linear attenuation coefficients, mass energy absorption coefficients, effective atomic numbers, electron densities, equivalent atomic numbers and energy absorption and exposure buildup factors. All these parameters have been calculated in the energy range of 0.015-15.0 MeV. The variation of parameters has been studied with incident photon energies, chemical composition and penetration depth of the various compensators. It is observed that up to 3 MeV and 14 mean free path (mfp): compensator with lowest values of the effective atomic numbers has the highest value of the buildup factor. Cerrobend has a particularly high value of the buildup factor near 100 keV. Above 3 MeV and 14 mfp: compensator with lowest values of the effective atomic numbers has the lowest value of the buildup factor. Thus a complete reversal in trend is observed at 3 MeV and 14 mfp. All these observation have been explained due to the dominance of the different interaction processes in different energy regions.

RESUMO

OBJECTIVE: To evaluate whether Medicare-style bundled payments are lower or higher for beneficiaries discharged from hospitals with postacute care (PAC) referrals concentrated among fewer PAC providers. DATA SOURCE: Medicare Part A and Part B claim (2008-2012) for all beneficiaries residing in any of 17 market areas: the Provider of Service file, the Healthcare Cost Report Information System, and the Dartmouth Atlas. STUDY DESIGN: An observational study in which hospitals were distinguished according to PAC referral concentration, which is the tendency to utilize fewer rather than more PAC providers. We tested the hypothesis that higher referral concentration would be associated with total Medicare bundled payments. DATA COLLECTION/EXTRACTION METHODS: The data represent a convenience sample of market areas that were defined by the locations of grantees from the ONC Beacon Community Program. PRINCIPAL FINDINGS: The four most-used PAC providers accounted for an average of 60 percent of patients discharged from hospitals in the sample. Regression analysis suggested that higher referral concentration was associated with lower Medicare costs per bundle. CONCLUSIONS: Hospitals that tend to use fewer PAC providers may lead to lower costs for payers such as Medicare. The study results reinforce the importance of limited networks for PAC services under bundling arrangements for hospital and PAC payments.

RESUMO

The residues of flubendiamide from berseem were extracted and cleaned up by the QuEChERS approach and analysed by liquid chromatography/mass spectrometry (LC-MS/MS). The dissipation studies on berseem were carried out by application of flubendiamide at five different dosages i.e. 24, 36, 48, 72 and 96 g a.i. ha(-1). The residues reached below determination limit (BDL) of 0.01 mg kg(-1) in 7, 10, 10, 15 and 15 days for 24, 36, 48, 72 and 96 g.a.i. ha(-1)dosages, respectively. Half-life (t1/2) of flubendiamide on berseem was observed to be 1.08, 1.88, 1.94, 2.26 and 2.27 days, respectively, at 24, 36, 48, 72 and 96 g a.i. ha(-1). Theoretical maximum residue contributions (TMRC) values reached below the maximum permissible limit (MPI) for 3, 5 and 7 days in treatments at 24, 36 and 48 g.a.i. ha(-1), respectively, whereas in case of higher dose treatments i.e. 72 and 96 g a.i. ha(-1), the residues of flubendiamide reached below MPI after 10 days of treatment. These data could provide guidance for the proper and safe use of this pesticide on berseem in India.

RESUMO

Accounting for 15 % of deaths worldwide, hypertension is often treated with hydrochlorothiazide (HCTZ) (50 million prescriptions annually). HCTZ has a <24-h duration of action, is less potent than chlorthalidone and all major antihypertensive drug classes, and is inferior to four antihypertensive drugs for cardiovascular event (CVE) reduction. If there were alternative diuretics, why prescribe HCTZ? Chlorthalidone is often offered as an alternative to HCTZ, but has limited pharmaceutical formulations. However, there are seven evidence-based, single-tablet, alternative diuretics. For reducing CVE, the following are superior to their comparators: chlorthalidone versus four antihypertensives in multiple hypertensive populations; indapamide versus placebo in elderly Chinese (and versus enalapril for left ventricular hypertrophy), triamterene-HCTZ versus placebo in elderly Europeans, amiloride-HCTZ versus three antihypertensives, and indapamide-perindopril versus placebo in three populations. Additionally, chlorthalidone-azilsartan and spironolactone-HCTZ are potent combinations The aldosterone antagonist component of the latter combination has been shown to reduce total mortality by 30 % in heart failure. Five of these seven have multiple dose formulations. Six cost $4-$77 monthly. In conclusion, based on both scientific and practical grounds, new prescriptions for HCTZ are rarely justified.

RESUMO

A study was conducted to observe the persistence, dissipation behavior, and risk assessment of acephate on brinjal fruit. Brinjal crop was sprayed with acephate 75 SP at 560 and 1120 g a.i. ha(-1) at fruiting stage followed by another application at 10-day interval. After sampling, the samples were extracted and cleaned up using quick, easy, cheap, effective, rugged, and safe (QuEChERS) technique, and the residues of acephate were analyzed with gas chromatography using flame photometric detector (FPD). The average initial deposits of acephate on brinjal fruits were found to be 2.54 and 4.07 mg kg(-1) following application of insecticide at 560 and 1120 g a.i. ha(-1), respectively. Residues of acephate reached below determination level of 0.10 mg kg(-1) after 7 days at recommended dosages and after 10 days at double the recommended dosages. The half-life of acephate was found to be 1.55 and 1.52 days, respectively, at 560 and 1120 g a.i. ha(-1). For risk assessment studies, theoretical maximum residue contributions (TMRC) were calculated and compared with maximum permissible intake (MPI). It was observed that TMRC values reached below MPI in 0-day samples at both recommended and double the recommended dosages. Therefore, it was concluded that if waiting period of 1 day is observed, there will be much reduced risk to consumers and the insecticide could be safely used for the protection of brinjal crop from insect pests.

RESUMO

The persistence pattern of chlorantraniliprole on berseem leaves and its risk assessment for the safety of cattle were studied. QuEChERS method was used for the extraction and cleanup of samples and the residues of chlorantraniliprole were estimated using high performance liquid chromatography (HPLC) and confirmed by Liquid Chromatograph-Mass Spectrometer (LCMS-MS). The dissipation studies on berseem were carried out by application of chlorantraniliprole at five different dosages i.e. 11.6, 17.1, 23.1, 34.7 and 46.2 g a.i. ha(-1). Average initial deposits of chlorantraniliprole were found to be 0.47, 0.61, 0.78, 1.15 and 1.31 mg kg(-1), respectively. The residues reached below determination limit (BDL) of 0.01 mg kg(-1) in 5, 7, 7, 10 and 10 days for 11.6, 17.1, 23.1, 34.7 and 46.2 g a.i. ha(-1) dosages, respectively. Half-life (t1/2) of chlorantraniliprole on berseem was observed to be 0.93, 1.14, 1.06, 1.00 and 1.33 days, respectively, at 11.6, 17.1, 23.1, 34.7 and 46.2 g a.i. ha(-1). It was found that the theoretical maximum residue contributions (TMRC) values reached below maximum permissible intake (MPI) on 0 day in berseem samples treated with chlorantraniliprole. These studies, therefore suggest that the use of chlorantraniliprole formulation at different dosages does not seem to pose any hazards to the consumers and a waiting period of one day is suggested to reduce the risk before consumption of berseem leaves. These data could provide guidance for the proper and safe use of this pesticide on berseem in India.
